Silver dollars have been a part of US currency since the late 1700s. The first silver dollars were minted in 1794, and the coins continued to be produced until 1935. The coins were made of 90% silver and 10% copper, and they were used as legal tender until 1964. The most popular silver dollar is the Morgan dollar, which was minted from 1878 to 1904 and again in 1921. The Morgan dollar was designed by George T. Morgan, and it features a portrait of Lady Liberty on the obverse and an eagle on the reverse. Other popular silver dollars include the Peace dollar, which was minted from 1921 to 1935, and the Eisenhower dollar, which was minted from 1971 to 1978. The value of old US silver dollars depends on the condition of the coin and the date and mint mark. For example, a 1921 Morgan dollar in good condition is worth around $30, while an uncirculated 1921 Morgan dollar is worth around $200. If you have old US silver dollars, you can take them to a coin dealer or have them appraised by a professional numismatist. You can also check online resources to get an estimate of the coins’ value. No matter what, it’s important to take good care of your coins to ensure they retain their value.
